It is well-known fact that sugar affects our teeth badly. Sugar provides food for the plaque found in our mouths and makes bacteria produce acid which damages the enamel of teeth by dissolving it. However, you should keep in mind that sour candy is even more harmful because it directly damages the enamel itself as well as feeding the bacteria. In addition, as sour candy is sticky, it clings to teeth, so saliva can’t just wash it away easily and it has more time to cause damage.
Some people believe they can avoid serious damage by brushing their teeth immediately after consuming sour candy. However, as strange as this may sounds, brushing can increase the damage as you can brush away some tooth parts that saliva can actually repair. But there are still some measures you can take in order to limit the negative effects of sour candy.
Of course, the best way is to avoid eating it or to reduce its consumption. It is a good idea to rinse your mouth with water after consuming sour candy as this will wash sugary leftovers. Use fluoride toothpastes and products because they are extremely beneficial.
